To all whom it may concern.-

Be it known that I, JOHN LEE JONES, of the city of Toronto, in the thecounty of York and Province of Ontario, Canada, have invented certainnew and useful Improvements in Oinder-Sifters, of which the following isspecification.

My invention relates to an improved sieving device for separating ashesfrom coal cinders,the object being to provide a simple, reliable, andeffective device into which the ashes and cinders can be deposited andby the action of gravity and the particular construction and arrangementof sieves and inclined chutes the ashes are fully separated from anddeposited in a receptacle'provided for them apart from the cinders. Iaccomplish this by the means illustrated in the accompanying drawings,in which similar numbers of refer ence refer to similar partsthroughout.

Figure 1 represents a perspective view of my improved cinder-Sifterhaving a portion of one side of the casing removed to show theconstruction thereof. Fig. 2 represents a vertical section through thesame at center to more fully show the construction. Fig. 3 represents asectional detail of a portion of the discharge-chute to show theinclines to discharge ashes from the top of said chute; and Fig. 4:represents a vertical central section of my improved sifter, taken atright angles to that shown by Fig. 2.

The casing, 1, is preferably square in plan and may be constructedeither from wood or sheet iron. In the top of the casing, 1, a lid, 2,is hinged to provide a cover to the sieve frame, 3 within the casing, 1.This sieve frame, 3, consists of two closed sides, 4, notched at eachedge and adapted to have alternately, sieves, 5, and inclines, 6,secured thereon, opposite one another, so as to first cause the cindersand ashes to pass overinclining sieves, 5, converging toward one anotherat their lower edges and allow the ashes to fall on the two diverginginclines, 6, which throw the ashes off to fall down to the ash pan, 7,inthe bottom of the casing, 1. Within the frame, 3, and at the top thereis a divide, 8, composed of sheet metal preferably to cause the cindersand ashes to fall outward against the first sieves 5, and again thereare other divides, S, but constructed of similar netting as the sieves,5, and having within these lower divides 8, agrooved incline, 9, in eachto throw the ashes outward through the sides, 4:, to fall down withinthe casing, 1, and by means of guides, 10, secured to the casing, 1, theashes are directed into the ash pan, 7. At the bottom of the sieveframe, 3, a chute, 11, is provided having a similar sieve bottom as thesieves, 5, and discharging the cinders outside the casing, 1.

Aslide door, 12, held in position on the easing, 1, by guides, 13, isprovided so as to retain the cinders within the chute, 11, when desired,and enable the ash pan from a stove or range from which the ashes andcinders are discharged into the top of the sieve frame, 3, being used toreceive the cinders when sieved or separated from the ashes.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. In a cinder sifter, the combination of the downwardly divergentinclined planes in the top of the sitter, a series of downwardlyconvergent sieves to again unitethe cinders beneath said inclinedplanes, a series of externally divergent inclined planes to throw offthe ashes falling from said convergent sieves, and a series of divergentsieves having grooved inclines beneath them to discharge the ashestransversely to said divergent inclined planes, substantially as shownand described.

' 2. .In a cinder sifter, having a sieve frame supported within theouter casing by the upper and lower ends of said frame, and having aspace between said casing and sieve frame, the combination of thedownwardly divergent inclined planes, in the top of the sifter, a seriesof downwardly convergent sieves beneath said inclined planes, a seriesof externally divergent inclined planes beneath said convergent sieveshaving grooved inclines beneath them, said divergent sieves and clinesbeing transverse to said inclined planes and convergent sieves andwithin the same, and a chute having a sieve bottom therein within theouter casing of the sifter, substantially as shown and described.
